Be it known that I, GILBERT W. Goon- RIDGE, o. citizen of the United States of Amer ice, residing et Bridgeport, in the'county of 5 Fairfield, in the State of Connecticut, have in- Vented certain new and useful Improvements in Incandescent-Lamp Sockets, of which the following is a speciiicetion;l

In mountingan incandescent electric lamp Socket upon axture or pipe, the cap is :first scrcwed'into -place and then the insulated lamp socket terminals are connected up to the Wires', and finally the socket shell is oonnected upto the dei. -In mountingthese sockets, particularly ey sockets, on fixtures and elsewhere, with ornamental huske, the key has to be rirra'nged to roect through one part of the ornamental ns and consequently'theshell hee'to be put on in afcertain position, conside red rotarily; With the construotonjofbeyonet joints or other shellfend cap festeni ye-x'iow'in use,'1tl\ose two perte,

O n oneor on both of t ese arts I the c orrugations fire many times repente and 60 ere arranged symmetrically. In the form illustrated, the number of corrugetions is the -sarne on both parte, except for those lost in the shell by the cutting of the key slot In the stendardsocket, twenty of these coruffetions are found a suitable number. As a means or-letching these two perte together, I prefer to yuse projections on one part and openings on the other. In the drtwing. I have lshown the shell afs-provided with two diametrieelly opposite outward rejections c, punched up outof the metai'o .the shell, While inthe Iiange of the eelptare cut out openings d, which are many times' repeated, and correspond in .number to thenumberof 75 c'orrugetions in the cap.
